Radio Shack Electronic Subwoofer Crossover Owner's Manual

Electronic Subwoofer Crossover
Your Electronic Subwoofer Crossover is de-
signed to give you excellent control over the
sound produced by your autosound system.
The crossover directs a selectable range of
lower audio frequencies to your subwoofer
speakers for increased bass response, and
blocks mid-range frequencies to enhance
sound clarity.
The crossover's features include:
Two Types of Inputs — let you use the
crossover with an autosound system that has
either line-out jacks or standard speaker out-
puts.
Low Pass Filter Selector — lets you adjust
the frequency filter to 50 Hz, 90 Hz, or 180
Hz to match your subwoofer speaker system.
Input Level Controls — let you adjust line
or speaker input levels to match your auto-
sound system.
Bass Boost Controls — let you boost the
selected subwoofer bass output by 12 dB.
INSTALLATION
You can easily connect this crossover. How-
ever, improper connections can damage
your crossover and other components in
your autosound system, and possibly your
vehicle's electrical system. Before you begin,
you should know:
• which wire is the power wire in your
vehicle's electrical system
• if your autosound system has line-level
or speaker-level outputs
OWNER'S MANUAL — Please read before using this equipment.
Before you install your crossover, carefully
read all the installation instructions in this
owner's manual.
Notes:
• Use audio patch cables with phono-type
connectors (available at your local
RadioShack store) to complete the low
level input/output connections.
• Use your autosound system's speaker
wires to complete the high level input
connections.
• Use 18-gauge wire (available at your
local RadioShack store) to complete the
power connections.
• Turn your autosound system's volume
all the way down before installation.
• Set the subwoofer amplifier gain (input
level) and crossover input level controls
to their midpoints.
Choosing a Mounting Location
Choose the mounting location for the cross-
over first, but do not mount it until you have
connected the wiring, adjusted the controls,
and confirmed that the crossover operates
properly with your system. By choosing the
location first, you can later mount the cross-
over without re-routing the wires.
Choose a mounting location that:
• is as near as possible to your autosound
system connections (It is important to
keep the audio cables as short as possi-
ble to reduce noise and interference)
